My face is looking dull and dark. What kind of treatment would be good?

I wonder why I get so dull and dark as I get older... T_T

It seems like my freckles are increasing too...

It's not like I'm trying to show off that I didn't take care of myself at all when I was young...

Which procedure will yield dramatic results?

I looked into it, and some people said it wasn't effective, so I'm hesitating. Are there any procedures you were satisfied with after getting them?

I wish my face would look a bit brighter and cleaner.
